Video transcript one of the most important animal behaviors is foraging or the search for food within an animals environment because without this ability, the animals not likely to be able to survive and reproduce. Predation on marine mammals mostly harbour seals was observed on 6 occasions, and no predation on fish was observed. For example, the chapters on population dynamics and community ecology chapters 11 and 12, point out convincingly that foraging behavior needs to be and, in some cases, has been, successfully incorporated into models of population and community dynamics, but, with the exception of studies of giving up density, the authors present little evidence that these concepts have had much influence on the conduct of empirical studies.
